Micko's Dream delighted Willie Mullins in his latest piece of work prior to Saturday's Martell Grand National.
His Irish trainer said: "Ruby Walsh rode him and came back saying that he was very happy with him.
"He will have another workout probably on Wednesday and then I will leave him and hopefully he will travel over on Thursday or Friday. I may even fly him across."
Jason Titley will ride Micko's Dream in the National as Walsh will be on Papillon for his father Ted.
